Bill is correct, that is where they are saying to put it. In Jax, SKUSA told us to put it 12″ behind the centerline of the front axle on the pods but with the new body work, 12″ is square on the centerline of the nerf bar! So they modified it to 10″ and it worked great.
Some of the new body work doesn’t have a good place to mount it on the side pod so that is why Stars is looking at doing it on the back of the seat. But that is causing some problems for depending on the installation of the seat, both the cross bar and the water pump are screwing up the signal! Many if not most new karts are now coming with the Unico style body work and there are no problems mounting the transponder on them. The back of the seat is almost impossible to get to with the pipe and all that stuff they have back there. Putting it on the back of the seat is not a good idea IMHO.
